    <activity

</application>

的活动：

VolleySingleton volleySingleton;
RequestQueue requestQueue;

TelephonyManager mTelephonyMgr;
String ANDROID_DEVICE_ID = null;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_login_check);

    mTelephonyMgr = (TelephonyManager) getSystemService(LoginCheckActivity.TELEPHONY_SERVICE);
    ANDROID_DEVICE_ID = mTelephonyMgr.getDeviceId();

    volleySingleton = VolleySingleton.getInstance();
    requestQueue = volleySingleton.getRequestQueue();

    sendReq();
}

logcat的

我在ANDROID_DEVICE_ID = mTelephonyMgr.getDeviceId();行收到错误。

我正在使用API 23进行测试。在我的其他应用程序中，此代码适用于API 23。
